WRENCH.

Application filed June 7,

This invention relates to a wrench for use in thrashing machinecylinders and other places difficult for access with anordinary wrench,the general object of the inventlon being to provide a chuck, with ahandle for holding the chuck carrying member and means associated at thefar end of the handle for turning the chuck. I v

This invention also consists 1n certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which 1- Figure1 is an elevation of the complete wrench.

Figure 2 is a section on line 2-2 of Figure 1.

Figure 3 is a section on line 3-3 of Figure 1.

Figure 4 is a section on line H of F1gure 1.

Figure 5 is a section on line 55 ure 1.

In these views, 1 indicates a hollow block which has its ends roundedand open and 2 indicates a hollow handle which is threaded in a boss 3formed on the upper face of the block adjacent one end thereof. A shaft5 is rotatably mounted in the handle 2 and has one reduced end passingthrough the block, the parts being held together by a cotter pin 6 whichpasses through a hole 1n the projecting end of the shaft. A portion ofthis reduced end is of square shape in cross section and a pinion 7 isinserted in the end of the block and has its square bore engaged by thissquare part so that the pinion will rotate with the shaft. A secondpinion 8 is rotatably mounted in the central part of the block throughmeans of the pivot pin 9, and this pinion 8 meshes With a third pinion10 which has a square bore engaging a squared part of a stem 11 of achuck 12 which is seated on the inner face of the block. The stem 11asses entirely through the block and is hel in place by a of Fig- 1926.Serial No. 114,302.

cotter pin 13 passing through a hole therein. Thus it will be seen thatwhen the shaft 5 is turned, its motion will be communicated to the chuckthrough means of the three pinions in the block.

A forked head or block 1d rests upon the handle 2 and the reduced upperend of the shaft 5 passes through holes in the prongs of this member. Aportion of this reduced part is squared and passes through the squaredbore of a ratchet wheel 15 which is placed between the prongs. A handgrip 16 is screwed to the threaded end of the shaft 5 which projectsabove the member 14 and thus holds the parts assembled. A double pawl 17is pivoted between the prongs and is adapted to engage the ratchet wheel15 and a spring pressed plunger 18 is carried by the member 14 and holdsthe pawl 17 with either one of its points in engagement with the wheel15. This arrangement of parts will enable the chuck to be driven ineither direction by properly setting the pawl 17. A handle 19 is slippedover the reduced end of the part 1 L so as to give proper leverage tothe wrench.

From the foregoing, it will be seen that I have provided means wherebythe chuck can be placed in engagement with an object to rotate theobject from the handle 1-9 in places where said object would beimpossible or difficult to reach by an ordinary wrench. By making thechuck removable, different sized chucks can be used and it can bereversed, if desired. The handles 16 and 12 provide various hand gripsfor holding the device to the work.

It is'thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claim.

Vhat I claim is:

ing a hollow block having its ends open, a threaded bushing on one sideadjacent one end of the block, a tubular handle having one end threadedin the bushing, a handle having a forked part fitting against the otherend of the handle member, a shaft A wrench of the class describedcomprispassing through the handle member, the Hook and the forked part,a hand grip connected with the upper end of the shaft and holding theforked part in place, ratchet 5 means connecting the forked part withthe shaft, a chuck rotatably carried by the block, a gear in the blockconnected with the chuck, a second gear in the block connected with theshaft and a third gear in the block and meshing with the other gears forcommunicating the movement of the shaft to the chuck.

In testimony whereof I affix my signature.

ARTHUR PRESTON NORTON.
